Abstract:
There is provided a particulate matter combustion catalyst which allows easy combustion of particulate matter collected on the particulate matter filter of a diesel vehicle, at a much lower temperature than by the prior art. The particulate matter combustion catalyst has a construction characterized by an NO oxidation catalyst wherein the catalyst component is carried on an acidic first carrier, and an NO2 decomposition catalyst wherein the catalyst component is carried on a second carrier. Preferably, the NO oxidation catalyst has a precious metal such as platinum carried on an acidic first carrier such as tungstic acid/zirconia, and the NO2 decomposition catalyst has a catalyst component selected from the transition metals carried on a second carrier such as titania, or alternatively, the NO2 decomposition catalyst has at least one metal selected from among alkali metals and alkaline earth metals and a precious metal such as platinum carried on a second carrier such as titania.
Abstract:
When a communication malfunction occurs in the transmission line between routers, and operation is carried out by a backup system control device, IP telephone terminals can connect to the backup system control device through the use of an IP address that is previously acquired from the address management device and saved. When the transmission line has been restored, the IP telephone terminals reconnect to the address management device so that operation can be carried out using an IP address under the control of the address management device. In a system that is operated by DHCP, it is thereby possible to construct a network that can be operated without installing a DHCP server at each remote station.
Abstract:
An exhaust gas purifying catalyst capable of exerting excellent NOx purifying capability even at high exhaust gas temperatures, exceeding 500° C., is provided.The catalyst is an absorption reduction-type NOx purifying catalyst comprising an NOx absorbent obtained by loading at least one alkali metal or alkaline earth metal on a crystalline ZrO2 composite oxide having added thereto at least one trivalent rare earth metal or divalent alkaline earth metal. Preferably, aluminum is further supported on the ZrO2 composite oxide. The NOx absorbent is considered to have an NOx absorption mechanism that an electron released from the alkali metal or the like enters into an oxygen vacancy part of the crystalline ZrO2 and this oxygen vacancy part functions as a strong base site for donating an electron to an electrophilic component such as NOx.

Abstract:
A joining connector system comprises: one connector having an engaging piece protruded on a connector housing thereof; and another connector having an engaging groove to which the engaging piece fits and which is formed in a connector housing thereof, the joining connector system being joined by sliding the engaging groove and the engaging piece with each other in a sliding direction. In such a structure, a protrusion having a shape tapered toward the sliding direction is provided near an end portion in a side in which a join of the joining connector is finished in the sliding direction, in at least one of the engaging piece and the engaging groove.
Abstract:
In a lever-actuated connector, on one end part of a side surface of a connector body (23) is formed a protruding lever insertion rib (27), into which an end (24C) of a lever (24) is inserted, which allows the end (24C) of the lever (24) to rock, and which extends upwardly and downwardly. An upper rib linking part (27A) that joins opposing walls that surround a lever insertion slit (31) is formed larger than a lower rib linking part (27B), and an upper through hole (32) communicates between the upper end surface of the upper rib linking part (27A) and the lever insertion slit (31). By adopting this configuration, when the lever insertion slit (31) is formed, die removal is done upwardly and downwardly, and it is not necessary to use a sliding die, thereby simplifying the die construction for the connector body (23), reducing the cost, and also enabling smooth insertion and fitting together of connectors.
Abstract:
A coupling connector includes: a connector housing of a first connector having an engagement piece formed by projecting an outer wall thereof; and a connector housing of a second connector having an engagement groove formed on an outer wall thereof. In the construction, the engagement piece is engaged with the engagement groove. The engagement piece and engagement groove are formed so as to be engaged with each other in an engagement direction intersecting perpendicularly to a coupling direction where the first and second connectors are coupled to each other. The connector housing of the first connector is slid to the coupling direction with respect to the connector housing of the second connector so that the engagement piece is engaged with the engagement groove so that the first connector and second connector are coupled to each other.
Abstract:
An automotive exhaust catalyst includes an alumina support having pores, an NO.sub.x, storage member loaded in the pores having a pore diameter of from 10 to 30.ANG. at least, and a noble metal element loaded on the alumina support. The automotive exhaust catalyst can store NO.sub.x, in a large amount in fuel-lean or oxygen-rich atmosphere, and inhibit the alumina support from sintering, because the NO.sub.x storage member is loaded in a highly dispersed manner.
Abstract:
A condenser (2), an electronic expansion valve (5), an evaporator (6), and a motorized suction throttle valve (8) are connected in series with a compressor. When a capacity is increased, the electronic expansion valve (5) is controlled to be in a throttling direction and the motorized suction throttle valve (8) is controlled to be in an unthrottling direction in association with the control of the electronic expansion valve (5), and when a capacity is decreased, the electronic expansion valve (5) is controlled to be in an unthrottling direction and the motorized suction throttle valve (8) is controlled to be in a throttling direction in association with the control of the electronic expansion valve (5). While a capacity control of a compressor by a throttle control is been carried out, such associated control is made between the electronic expansion valve (5) and the motorized suction throttle valve (8), realizing a fine temperature control in a refrigerating machine without hunting.
